The people responsible for the 'Saw' franchise have said that the seventh entry, 'Saw 3D,' will be the last one. If that's true -- and there's no reason to believe it is -- then it's a fitting conclusion. Part 7 takes us back to the beginning in many ways, wrapping up some loose ends and reminding us of how goofy the whole thing has become. Even better, you get to pay extra for your ticket and wear dark glasses while you watch it!
You will recall that Jigsaw (Tobin Bell) -- the cancer-ridden sociopath with the God complex who tortures people until they appreciate life again -- died, like, four movies ago. He lives on through the magic of flashbacks, though, and also thanks to the tireless efforts of a police detective named Hoffman (Costas Mandylor), who continues to find Jigsaw-worthy victims in need of a life lesson. Unmentioned but surely an integral part of Jigsaw's operation are the teams of engineers who design and build all of his devices, doing so in secret and in complete defiance of zoning laws and safety codes.
In part 7, 'Saw 3D,' the final chapter, in 3D, Hoffman is still up to his (that is to say Jigsaw's) old tricks, but now his fellow cops are on to him. Jigsaw's widow, Jill (Betsy Russell), has told a detective named Gibson (Chad Donella) what she knows, which is plenty. In exchange for this, Hoffman will probably try to kill her. This is fair.
